SUSE SLED12 / SLES12 Security Update : openssl (SUSE-SU-2015:0541-1)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

OpenSSL was updated to fix various security issues.

Following security issues were fixed :

- CVE-2015-0209: A Use After Free following
d2i_ECPrivatekey error was fixed which could lead to
crashes for attacker supplied Elliptic Curve keys. This
could be exploited over SSL connections with client
supplied keys.

- CVE-2015-0286: A segmentation fault in ASN1_TYPE_cmp was
fixed that could be exploited by attackers when e.g.
client authentication is used. This could be exploited
over SSL connections.

- CVE-2015-0287: A ASN.1 structure reuse memory corruption
was fixed. This problem can not be exploited over
regular SSL connections, only if specific client
programs use specific ASN.1 routines.

- CVE-2015-0288: A X509_to_X509_REQ NULL pointer
dereference was fixed, which could lead to crashes. This
function is not commonly used, and not reachable over
SSL methods.

- CVE-2015-0289: Several PKCS7 NULL pointer dereferences
were fixed, which could lead to crashes of programs
using the PKCS7 APIs. The SSL apis do not use those by
default.

- CVE-2015-0293: Denial of service via reachable assert in
SSLv2 servers, could be used by remote attackers to
terminate the server process. Note that this requires
SSLv2 being allowed, which is not the default.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
